Satellite Earth Stations and Systems (SES) - Fixed and in-motion Wide Band Earth Stations communicating with non-geostationary satellite systems (WBES) in the 11 GHz to 14 GHz frequency bands - Harmonised Standard for access to radio spectrum
The present document specifies technical characteristics and methods of measurements for fixed and in-motion Earth
Stations communicating with non-geostationary satellite systems (WBES) in the 11 GHz to 14 GHz FSS frequency
bands, which have the following characteristics:
• The WBES is further defined as one of two classes of Earth stations, class A and class B. The clauses in the
present document apply to both classes unless separately delineated.
• The WBES is designed for both in-motion and stationary operation.
• The WBES operates in-motion on various platforms such as trains, maritime vessels, aircraft and other
vehicles and, therefore, may be subject to occasional disturbances and interruptions in the satellite link.
• The WBES is operating as part of a satellite system used for the provision of broadband communications.
• The WBES is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a mobile platform.
• The WBES comprises one or more emitters and the system overview as given in figure 1 should be interpreted
accordingly.
• The transmit and receive frequencies are shown in table 1.
The WBES transmits within the frequency range from 14,0 GHz to 14,50 GHz.
• The WBES receives within the range from 10,70 GHz to 12,75 GHz.
• The Class A WBES transmits at elevation angles of 35° or greater, relative to the horizontal plane.
• The Class B WBES transmits at elevation angles of 25° or greater, relative to the horizontal plane.
• The WBES uses linear or circular polarization.
• The WBES communicates with non-geostationary satellites.
• The WBES is designed for unattended operation.
• The WBES is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of
the present document.
The present document applies to the WBES with its ancillary equipment and its various telecommunication ports, and
when operated within the boundary limits of the operational environmental profile as required by its intended use and
when installed as required by the intended use or in the user documentation.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.
Satelitske zemeljske postaje in sistemi (SES) - Nepremične in premične širokopasovne zemeljske postaje, ki komunicirajo z negeostacionarnimi satelitskimi sistemi (WBES) v frekvenčnih pasovih od 11 GHz do 14 GHz - Harmonizirani standard za dostop do radijskega spektra
Ta dokument določa tehnične lastnosti in metode merjenja za nepremične in premične zemeljske postaje, ki komunicirajo z negeostacionarnimi satelitskimi sistemi (WBES) v frekvenčnih pasovih fiksnih satelitskih storitev (FSS) od 11 GHz do 14 GHz, z naslednjimi značilnostmi:
• Negeostacionarni satelitski sistem je dodatno opredeljen kot dva razreda zemeljskih postaj, razred A in razred B. Točke v tem dokumentu se uporabljajo za oba razreda, razen če obstaja ločena opredelitev.
• Negeostacionarni satelitski sistem je izdelan za mobilno in stacionarno delovanje.
• Negeostacionarni satelitski sistem deluje na različnih platformah, npr. na vlakih, morskih plovilih, letalih in drugih
vozilih, pri čemer lahko pride do občasnih motenj in prekinitev v satelitski povezavi.
• Negeostacionarni satelitski sistem deluje kot del satelitskega sistema, ki se uporablja za zagotavljanje širokopasovne komunikacije.
• Negeostacionarni satelitski sistem zajema vso opremo, električno in mehansko, od same antene do
vmesnikov z drugo komunikacijsko opremo na mobilni platformi.
• Negeostacionarni satelitski sistem zajema enega ali več oddajnikov, pri čemer naj bi se pregled sistema na sliki 1 razlagal v skladu s tem.
• Frekvence oddajanja in sprejemanja so prikazane v preglednici 1.
Negeostacionarni satelitski sistem oddaja v frekvenčnem območju od 14,0 GHz do 14,50 GHz.
• Negeostacionarni satelitski sistem sprejema v območju od 10,70 GHz do 12,75 GHz.
• Negeostacionarni satelitski sistem razreda A oddaja pod višinskimi koti 35° ali večjimi glede na obzorje.
• Negeostacionarni satelitski sistem razreda B oddaja pod višinskimi koti 25° ali večjimi glede na obzorje.
• Negeostacionarni satelitski sistem uporablja linearno ali krožno polarizacijo.
• Negeostacionarni satelitski sistem komunicira z negeostacionarnimi sateliti.
• Negeostacionarni satelitski sistem je izdelan za nenadzorovano delovanje.
• Negeostacionarni satelitski sistem se krmili in nadzira z napravo za krmiljenje omrežja (NCF). Naprava za krmiljenje omrežja ne spada na področje uporabe tega dokumenta.
Ta dokument se uporablja za negeostacionarni satelitski sistem s pomožno opremo in različnimi telekomunikacijskimi vrati, ko ta deluje znotraj mejnih vrednosti obratovalnega okoljskega profila, kot zahteva predvidena uporaba, ter ko je nameščen v skladu z zahtevami predvidene uporabe ali v skladu z zahtevami dokumentacije uporabnika.
OPOMBA: Razmerje med tem dokumentom in bistvenimi zahtevami člena 3.2 Direktive 2014/53/EU [i.1] je podano v dodatku A.
